The Edmonton Oilers were simply too slick for the Chicago Blackhawks on Wednesday night, skating to a convincing 4-1 victory.

It marked Edmonton's fifth straight triumph over Chicago at Rexall Place.

Edmonton's Denis Grebeshkov squeezes Patrick Sharp off the puck in a 4-1 Oilers win.

Joni Pitkanen paced the Oilers with one goal and one assist, while Jarret Stoll, Dustin Penner and Ethan Moreau had the other goals.

Rookie Sam Gagner contributed two assists and Mathieu Garon stopped 40 shots in a tidy effort for the Oilers (25-26-5), fresh off Monday's 5-0 whitewash of the Calgary Flames.

Patrick Sharp opened the scoring with a power-play goal for the Blackhawks (23-25-5), who have lost five consecutive outings.

Sharp tipped Duncan Keith's point shot for his 24th goal of the season with 43 seconds left in the first period.

Stoll tied it at 1-1 with a power-play goal of his own, slapping his ninth past Blackhawks netminder Patrick Lalime 2:16 into the second period.  

Penner put the Oilers ahead 2-1 with his 17th on a slick deflection off Gagner's hard pass into the crease at the 8:10 mark.

It was Penner's sixth goal in nine games versus Chicago.

Moreau scored 34 seconds later on a similar play, cruising through the crease in time to tip Ladislav Smid's centring pass by Lalime for his fifth.

Pitkanen completed the scoring 51 seconds into the third period, circling into open ice and unleashing a slapshot that fooled a screened Lalime.

It was Pitkanen's seventh goal this season.
